The invention relates to tension devices. and has. particular reference. to an improved window clamp.- of' simple construction capable of applying tensionto: a window frame for preventing a rattle and other noise caused by a loose fitting of said frame in its window lamb.

An object of. the invention resides in the provision of'a. clampor similar device for application to Window frames and which will provide tension.

means of a resilient nature for preventing nOise caused: by rattling of the window frame.

The anti-rattlingdevice. of the invention has a curved central section on a leg portion thereof forming a. resilient part of arcuate shape and which is compressed between the window frame and the iamb when the device is inserted in the space between these elements. The action of fastening. the device tov the window frame functions to embed the prongs provided by the device in. the window frame, and thus the parts are maintained. in secured relation during operation.-

Another object of the invention is to provide a. metal clamp: as above described having means for readily securing the same to a window frame and which. will function in a, manner that assists in retaining the clamp in operative position on the frame.

With these and various. other objects: in. view, the invention may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specification, drawings and claims appended hereto;

In the drawings which illustrate an embodiment of the device: and wherein like reference characters are used to designate like parts- Figure l is a perspective view of a tensioning device constructed in accordance with the pres.- ent invention;

Figure 2 is an elevational view, parts being shown in section, to illustrate the location and manner of securing. the device. to .a window frame;

Figure 3' is a sectional view taken along line 3-3 of Figure 2 showing the device in front elevation;

Figure 4 is a fragmentary elevational view of a window frame showing. another adaptation of, the present window clamp; and

Figure 5 is! a sectional View taken substantially along line 5-5 of Figure 4.

Referring to the. drawings, the tensioning device or window clamp selected for illustrating the present invention is shown in perspectivevin Figure: 1 and; which. view clearly illustrates the several constructional features comprising the 4 Claims. (Cl. 292-76 present improvements.

2 Y The said device is prob erably formed from a single strip of spring metal of any desired width, primarily depending on the. type of frame. to which the device is to 136,31)!

plied. The metal strip is bent to form a leg portion Ill and a right angle flange portion H. The leg portion is characterized by the curved section l2 and by the end sections l3' and M. The free end It is provided with a punched opening I5 and the metal below the opening is. separated and bent to form an inwardly clirectedprong. Hi.

The sections, l3 and ll. of the metal strip: lo.- cated above and below the arcuate section 12-, respectively, are bent so as to lie in substantially the same planeat least when pressure is appliedv to the arcuate section 12 as is evident from. an in,- spection of Figure 2. The leg portion In is terminatediby the; right angle bend l'lforming the top flange I. I. Said top flange is additionallybent' to provide the depending. securing spike 18. The

spike I8 is accordingly located in spaced parallel relation as regards the leg portion and the distance between the parts. depends on the length of the top flange l I. In order to facilitate cm trance of. the spike l8 into the frame of a window or the like, the same is formed in the. shape of an arrow having the pointed end [9.

As: shown in Figure 2, the anti-rattling device of the invention. has been applied to the lower window frame 20, the frame structure of'which is formed in part by top horizontal member 2|, a side vertical member 22, and. the glass pane 23.- The lower frame is:- disposed in associated relation with an upper frame indicated generally by Li andzwhich includes the vertical frame mem ber 25 and the glasspane 26. The window frames are located within thewindow opening provided in part. by vertical side members. such as 21 which comprise the window jamb and which provide the channels: 28. and: 3-0 for receiving the lower and upper window frames, respectively. The partition member 31 separates channel 28 from chan nel 30 and the frames. are accordingly positioned" on: the respective sides of this partition member.

Upon insertion of the present window clamp in the space between the window frame and the windowjamb, the same will be subjected to pressure'and which is applied against the resilient seciton l2. In the manufacture of the window clamp, it is desirable that the resilient section-- l2 have; suffiicient curvature, which; however, mayvbeli'mited in extent so that the device will" atv all timesprovide'. the desired tension when: in;- serted between frame members such as thc lowor window and Jamie, as shown in Figure' z.

16, which prong is bent inwardly, being located out of the plane of the free end section 14. The

action of prong I 6 in embedding itself in the wood of frame member 22 is practically automatic and results from the insertion of the device between the window frame and the jamb which causes pressure to be applied to the arcuate section 12. This pressure tends to flatten the arouate section with the result that sufficient pressure is applied to the depending end M to cause prong Hi to embed'itself in the window frame."

' It is entirely possible to apply one or more of the anti-rattling devices of the invention to a single window frame, one being applied at each corner, for example. The tension exerted by the resilient section 12 is maintained during movement-of the window frame and also in all locations vertically, to which the frame may be opened. Any rattling of the frame and other noise due to a loose fit of the frame is eliminated. It is also possiblefor the present device to have a limited sealing function by sealing off the space between the window frame and its jamb.

The most important feature, however, is the uniform application of tension to eliminate noise and rattle, and which tension may be sufficient in many cases to provide .the necessary friction against free and easy movement. of the window, thereby counteracting to a degree at least/the counterbalancing function of the conventional window weights.

It will be observed that the spike l8 and the prong I6 are directed toward each other in op posed'relation. Their action is to retain the device in secured relation on the'window frame, since when the window is moved downwardly the prong I6 is effective as a fastening element and when moved upwardly the action is to assist in maintaining the spike 18 in its lation' in the frame.

In Figure 4 the window clamp of the invention has been-secured to the lower window frame and located between the inside molding 32. As a resultthe window frame is yieldingly urged outwardly and held in contact with partition mem'- ber 31. The bottom horizontal frame'member 33 of the lower window frame is suitably secured to the side vertical member 22 for retaining the glass pane 23-. To prevent transverse movement of the window frame, the-window clamp has been applied to the front surface of frame member 33, being located between the member and the inside molding 32. The device is applied in a manner as described, that is, by embedding the spike 18 in the frame member, which securely holds the device in place on the window frame, preventing inadvertent removal of the device even-when the window is moved upwardly in an opening direction'; Theretaining action of spike l8 issupplemented by prong it which automatically embeds itselfin. the front surface of frame member 33. The'arcurate and resilient portion 12 of the present tensioning device is thuspositioned between thewindow frame-and the inside molding 32 to apply pressure to the molding and to thus yieldembedded reingly force the window frame into contact with partition member 31. Any tendency of the device to rattle caused by movement of the window frame transversely of channel 28 is effectively prevented and the action of the tensioning device also facilitates the sealing of the window frame since close contact is maintained with the partition member 3|.
